Wild Hedgehog Supplementary Feeding Evidence

Supplementary feeding of hedgehogs in gardens is widespread, and evidence on its welfare benefits and risks guides best practice.

Key Facts

Supplementary feeding increases hedgehog body weight and breeding condition in some studies
High-sugar, high-salt, or inappropriate foods cause health problems
Meaty cat or dog food and specialist hedgehog food are appropriate supplements
Water provision is as important as food, especially in dry summers
Feeding stations reduce competition from foxes and badgers and allow monitoring

Welfare Considerations

Hedgehogs in gardens with appropriate supplementary food and water show better body condition heading into hibernation. However, feeding inappropriate food causes nutritional harm. The welfare benefit of correct supplementary feeding is clearest in late summer and autumn when body condition before hibernation determines overwinter survival.

What You Can Do

Provide meaty cat food and fresh water for visiting hedgehogs
Use a feeding station that excludes larger animals
Avoid milk, bread, and mealworms which are inappropriate hedgehog foods
